What are Earth’s four main Geological subsystems?
Lithosphere, Hydrosphere, Biosphere, Atmosphere
What is another name for the Lithosphere?
Geosphere
The Lithosphere consists of?
(land) the Earth’s crust, upper and lower mantle as well as the inner and outer core

What does the Hydrosphere consist of?
all forms of Earth’s water (vapor, liquid and ice)
What are the 5 layers of the Atmosphere (give description of each)?
Troposphere (birds, planes)
Stratosphere (jet stream)
Mesosphere (rocks, meteors)
Thermosphere (satellites)
Exosphere (other unknown solar systems and has no boundaries)
Note:
The Ozone layer blocks radiation from the sun.
The higher the layer of atmosphere, what happens?
The thinner it becomes (less oxygen) gradually decreasing eventually leading to space.

What are the main elements of the atmosphere?
carbon, nitrogen, oxygen, hydrogen
Differentiate between open and closed systems.
Open systems transfer both energy and matter while a closed system transfer energy not matter.
The spheres of the Earth are an example of what system? (open or close)
Open system
What is an example of a closed system?
